7 Claims.v (Cl. 226-14) My invention relates to improvements in carton filling machines, the objects of which are to provide means whereby cans, bottles or the like may be received from a conveyor and filled into a carton row by row and in one or more tiers according to the capacity of the carton; to provide means whereby the feeding mechanism may be readily adjusted according to the diameter and height of the packages .tobe packed and generally to provide a simple and convenient machine for this purpose, which is particularly suitable for use by wholesale grocers and other commodity purveyors who pack a multiplicity of commodities of various sizes and find it necessary in view of a relatively small pack to change from one size of carton to another after a few hours The invention consists essentially of a hinged platform vertically movable within an open carton and means for receiving packages and for filling same into said carton, and means for upsetting the loaded carton, after filling, for closing, as will be more fully described in the following specification and shown in the accompanying drawings, in which:- i

Fig. 1 is a plan view of the invention.

Fig. 2 is a side elevation.

Fig. 3 is a sectional view of the carton tilting, table taken on the line 3--3 of Figure 1.

Fig. 4 isa detail view of the piston valve control taken. on the line 4-4 of Figure 1.

Fig. 5 is a diagrammatic view showing the rows of cans being filled into the carton.

Fig. 6 is an enlarged perspective view' of the carton filling tray and front guard.

Fig. 7 IS a perspective view of the feed tray stops. g

In the drawings like characters of reference indicate corresponding parts in each figure.

The numeral I indicates a base supported upon legs 2 on some of which supports 3 are adjustably secured for the purpose of supporting a carton 4 by its lower flaps 5. Mountedadjacent the end of the base is a ram 6 vertically movable within a cylinder I, which ram is adapted to be raised by fluid pressure entering the base of the cylinder through the pipe 8 and controlled by a suitable valve, not shown. Secured to the top of the ram 6 is a bracket 9 supporting at its upper extremity a table I0, which is detachably carried by a hinge I I connected to the bracket 9. A fork I2 extends inwardly from the bracket 3 in which an oscillating cylinder I3 is mounted. This cylinder is provided with a piston rod I4 connected at its outer end with a hinge II to tilt the table II] as fiuid pressure enters the cylinder I3 from an inlet pipe I5, from a suitably controlled supply.

Depending from the bracket 9 is a vertical bar I6, see Figures 2 and 3, having adjustably 5 spaced thereon. a plurality of inclined stops II which are adapted to progressively engage a pawl I8 to stop the downward movement of the ram Band the table III as the pressure thereto is released and to pass said pawl as the table is raised. 10 The removal of the pawl from engagement with any stop is effected by a foot pedal l9 through a connecting rod 20.

The numeral 2I indicates a conveyor for delivering cans or otherpackages to be packed, onto i5 a tray 22, which is provided with longitudinal slots 23. The tray is secured to the outer end of a piston rod 24, which is reciprocated within a horizontal cylinder 25.

V The tray 22 is detachably mounted and is subject to substitution of other trays of varying widths according to the size of carton to be filled.

Suitably mounted to one side of the tray and to travel therewith is a spacer bar 26 upon which a plurality of stops 2! are adjustably carried.

7 These stops have an inclined upper edge 28 and a vertical forward face 29, the purpose of which will hereinafter appear. The outside faces of the stops are provided with a notch or gate 30 intermediate their length and a tapered approach 3! at opposite ends except in the rearmost stop referred to as 21A, which has a tapered approach 3i at its forward end and a lug 32 at its rearward end, which projects beyond the approach 3 I. The cylinder 25 is supplied with fluid pressure and exhausts through pipes 33 and 34, which lead from a piston valve generally indicated by the numeral 35, which valve is provided with intake 36 and exhausts 31 and 38. The .valve has a piston 39 of the bobbin type and an elongated rod 40 40 supported at its outer end in a bearing 4|. The rod is provided with a key 42 engaging a complementary groove in the bearing to prevent it from turning and is fitted at its outer end with a rocking lever 43 having a counterweight 44 or 45 other suitable means for urging the lever towards the spacer bar 26'and the stops 21, see Figure 4.

The lever 43 is provided. with a web 45 which is adapted to enter the gate 30 of any of the stops 2! and also to be engaged by the lug 32 of the stop 21A.

A guide bar 46 is supported above the tray 22, see detail in Figure 6, which bar slopes downwardly as at 41 to the surface of the tray. The bar is aligned with one of the side walls of the 5.5

messes immediately above the carton, means for advancing each row of articles with the tray into the carton, and means for thrusting all the articles forwardly in advance of the final forward movement of the tray.

7. In a carton filling machine having a carton support, an article reciving tray, means for aligning a. row of articles upon the tray, means for advancing the tray progressively to receive successive aligned rows of articles thereon and for thrusting the articles and the tray into position immediately above the carton, and means for holding the articles immovable during the withdrawal of the tray.
